您如何从ac＃客户端发送补丁请求？

Question

我有一个执行此操作的powershell脚本：

    $uri = "$($tfsUri)/$($teamproject)/_apis/build/builds/$($buildID)?api-version=2.0"
    $data = @{keepForever = $keepForever} | ConvertTo-Json
    $response = $webclient.UploadString($uri,"PATCH", $data) 

我正在尝试使用Webclient在C＃中重写它。

WebClient client = new WebClient();
client.Encoding = System.Text.Encoding.UTF8;
string reply = client.UploadString(url, "keepForever = true");
Console.WriteLine(reply);

但我得到：远程服务器返回错误：（401）未经授权。

这是TFS 2015 VNext，如果有帮助的话。

Answer 1

您在对UploadString的调用中缺少METHOD。

string reply = client.UploadString(url, "keepForever = true");

应该：

string reply = client.UploadString(url, "PATCH", "keepForever = true");

401是未经授权的，因此还要查看在Powershell中是否有登录或加入会话的步骤，您需要在C＃中复制该步骤。

Answer 2

为了发送PATCH请求，您可以使用WebClient.UploadData 。

string data = "keepForever = true";
WebClient client = new WebClient();
client.Encoding = System.Text.Encoding.UTF8;
string reply = client.UploadData(url, "PATCH", System.Text.Encoding.UTF8.GetBytes(data));
Console.WriteLine(reply);
